GLOBE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 448,119, dated March 10, 1891. Application filed April 17, 1890. Serial No. 343,434. (No model.)

To all whom it may concern.-

Be it known that I, HOWARD R. BURK, of the city, county, and State of New York, have invented a new and Improved Globe-Holder, of which the following is a full, clear, and exact description.

The invention relates to holders for retaining globes on gas or other fixtures.

The object of the invention is to provide a new and improved globe-holder which is simple and durable in construction, is readily applied to a gas or other fixture, permits of conveniently attaching or detaching the globe, and securely holds the globe in place when attached, whether the globe is expanding by the heat of the flame or contracting on cooling.

The invention consists of a globe-holder frame, a series of springs secured on the said frame and adapted to press onto the globe, and arms extending from the free ends of the said springs and passing through slots in the said frame to the outside of the latter to form convenient handles for manipulating the said springs.

The invention also consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improvement. Fig. 2 is a side elevation of the same as applied, with parts in section; and Fig. 3 is an enlarged sectional side elevation of part of the improvement with the globe in place.

The improved globe-holder A is provided with a frame B, having a base G fastened in the usual manner on the burnerD of thegas or other fixture on which the holder is to be applied. The base 0 supports on its outer end a ring E, having an upwardly-extending flange F, formed on 'its' outside, as is plainly illustrated in Fig. 3. On the ring E is adapted to rest the lip or outwardly-extending flange of the globe G, as is plainly shown in Fig. 3. The globe is held in place on the ring E bya series of springs H, each fastened at one end at H to the inside of the flange F and adapted to press at its free end against the outside of the globe directly above the lip of the latter, as is plainly shown in Fig. 3. From the free end of each spring I-I extends outward an arm I, passing through a slot F in the flange F, and having on its outer end a knob or button J for conveniently manipulating the spring and attaching or detaching the globe. In order to hold the springs H in the proper place and to guide the arms I, inwardly-extending flanges F are formed around the slots F in the flange F, as is plainly shown in Fig. 3.

In order to attach a globe on the frame B, the lip of the globe is pressed under the free ends of the springs H. The latter are drawn outward by the operator pulling on the buttons or knobs J, and when the lip of the globe rests entirely on the ring E the operator, by releasing the buttons J, permits the several springs H to press inward against the globe, thus holding the latter in place. As the free ends of the springs H press on the globe above the lip, as is plainly shown in Fig. 3, the globe is not only held in place laterally, but is also prevented from moving upward. It is understood that the several springs H are drawn out successively in order to place the globe in position,and then the springs are released, as above described. It will be seen that when the globe expands by the heat from the flame of the burner D the springs H give sufficiently to compensate for the expansion of the globe, so that the latter is not broken, as is so frequently the case with holders held on the frames by means of screws. When the globe cools after the flame is extinguished, the springs H move inward to compensate 'for the contraction of the globe, so that the latter is under all conditions hold securely in place.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. A globe-holder oomprisinga frame, a series of springs secured to the said frame and adapted to press on the globe, and arms formed integral with and extending from the free ends of the said springs and passing through slots in the said frame to the outside of the latter to form convenient handles for manipulating said springs, substantially as shown and described.

2. In a globe-holder, the combination,\vith a frame provided with a flanged ring, of a series of springs secured to the inside of the flange of the said ring and projecting inward, and handles formed on the free ends of the said springs and passing through slots in the said flange to the outside of the latter to form handles for conveniently manipulating the said springs, substantially as described.

3. In a globe-holder, the combination,with a frame provided With a flanged ring, of a series of springs secured to the inside of the.
